Hi hezzer926. Do you have copies of your test results? It is always good to get them.
What dose of Doxy are you taking?
Babesiosis is simliar to malaria. It needs to be treated with an anti-malarial (often Mepron) together with certain antibiotics (Zithromax, Biaxin, or Ketek). I have not heard of Doxy being used to treat it.
